In this contribution the Airbus 'design to safety and design to operational reliability' integrated process, defining how safety functions can be derived from safety requirements and can be integrated in the design process, is presented. For Airbus aircraft, the determination of safety functions and their implantation in systems are completely integrated and safety functions are systematically defined in order to fulfil all safety requirements and, particularly, the 'no single failure that can lead to catastrophic repercussions'. Safety functions can be implemented in independent safety systems (back-up systems, protection systems) or integrated in the system architecture. The key point for determination, design and implementation of safety functions is a complete and validated safety requirements list taking into account real operational and maintenance conditions. The reuse of experience through the 'Airbus prevention process' leading to elaborated 'experience design rules' is being considered as 'design requirements', which contribute efficiently to complete the safety/operational reliability requirements list, and the lessons learned from experience is a means of continuous improvement of the design process for safety and operational reliability benefits. The reuse of experience is a condition for developing safe, operationally reliable, and mature systems
